Not sure that's the right question to ask, in my opinion the right question is, "for this dose of the vaccine, at this time, do the future risks of not getting the vaccine outweigh the future risks of getting the vaccine". You have to calculate that for each dose of the vaccine, and for various proposed vaccine dose spacing options. If there are more than one vaccine available for use, add permutations for those.
Unless you're part of that one tiny age group that's really not that important anyhow<p>> with one exception. Men under 40 who received a second dose of the Moderna vaccine had a higher risk of myocarditis following vaccination.
For anyone interested, here's the study.
